Saadna ASD & IPAD Marketing EMIF06-SD02F3 SPACE SAVING SINGLE CHIP IPAD MEMORY CARD TRANSCEIVER IN Flip-Chip An increasing number of mobile phones now include removable memory cards. Feature-rich phones often need external memory storage to transfer data to printers, computers or other mobile phones. These memory cards are called SD (Secure Digital) or MMC (Multi Media Card) and exist in various formats: Mini-SD, μSD, SD, MMC, Trans-flash, etc. The design of the interface between these memory cards and the CPU must provide: High ESD protection due to the exposure of the external memory card slot to the outside world Efficient EMI filtering to protect data lines against disturbances from RF frequencies Smart signal conditioning which consists of resistors in pull-up or pull-down to avoid data line bus floating Fast level translator to shift the 1.8 V CPU data to 2.9 V memory card data, in both directions (either when reading or writing the memory), without slowing-down the data rate Accurate and stable power supply to the memory card, that can be powered-off for low-power devices Single Chip Solution The EMIF06-SD02F3 is an IPAD™ that interfaces 4bit data signals between SD or MMC memory cards and the baseband CPU.

Cheron ASD & IPAD Marketing ACST2 Series NEW HIGH IMMUNITY, ROBUST 800 VOLT AC SWITCHES The home appliance industry is shifting towards electronic control on a worldwide basis. Together with this trend, electronics can now cope with AC mains constraints where high voltage robustness and transient voltage compatibility are the key challenges. ST has designed the ACSTM and ACTS devices to control the numerous AC loads necessary for the appliance process. These AC switches meet the requirements of reliability, compactness and mass production capability. The new ACST2 series belongs to the AC power switch family built around the ASD technology. These high performance devices are adapted to home appliances or industrial systems and drive loads up to 2 A such as pumps, fans or solenoids. ACST2 embeds a Triac structure with a high voltage clamping device to absorb the inductive turn-off energy. Thanks to its crowbar auto-protection technology it withstands line transients such as those described in the IEC 61000-4-5 standards. This component needs a low gate current to be activated (I GT < 10 mA) while providing a high electrical noise immunity such as those described in the IEC 61000-4-4 standards.

Renard ASD & IPAD Marketing ESDAVLC6V1-1BM2 THE LOWEST LINE CAPACITANCE BI-DIRECTIONAL TRANSIENT VOLTAGE SUPPRESSOR DIODE AVAILABLE The introduction of high bandwidth functions in portable applications has drastically increased the need for very low capacitance ESD protection devices. As an example, new cellular phones are now embedding such features as high resolution displays, high sensitivity keypads and USB and video interfaces. Such interfaces require a high level of ESD protection together with a low impact on signal integrity. In fact very low capacitance protection diodes are required. Lowest On The Market To support this high demand on very low capacitance ESD protection, ST has recently introduced the ESDAVLC6V1-1BM2, a single Transient Voltage Suppressor (TVS) diode with only 7 pF line capacitance. This is the lowest line capacitance ESD protection diode available on the market today. The ESDAVLC6V1-1BM2 is available in a bi-directional configuration with a working voltage of 5 V and a minimum breakdown voltage of 6.1 V. With a capacitance of 7 pF, this device is appropriate for transient protection of high frequency data lines and signal interfaces. Designed to protect against the transient environments of IEC 61000-4-2 (ESD), all devices are tested up to 15 kV ESD contact and air discharge. Key Features VBR min = 6.1 V ±15 kV ESD protection (IEC 61000-4-2) Very low capacitance: 7 pF max @ 0 V Very low leakage current (100 nA max @ 3 V) Standard SOD882 package Key Benefits High ESD protection (±15 kV in IEC61000-4-2) Supports high bandwidth applications Ultra small package - only 0.6 mm2 Standard SOD882 Package In addition to being cost-effective, using the surface mount SOD882 package for transient protection reduces the space required for ESD protection components. Packaged in the standard SOD882 plastic case, this device can substitute similar 0402 outline configurations. The ESDAVLC6V1-1BM2 should be placed as close as possible to a connector or a sensitive IC component.

Rabier ASD & IPAD Marketing DSL01-008SC5 /-016SC5 ADSL2+ AND VDSL COMPLETE MODEM PROTECTION IN ONE TINY PACKAGE With the increase in the use of video phones it has become critical to further increase the bandwidth of telecommunication lines. When using ADSL2+ (2.2 MHz) or VDSL (12 MHz) it is mandatory to minimize losses and distortion on twisted pairs. Whatever the signal, equipment must comply with various surge standards that simulate lightning and power faults, such as ITU-T-K20/21, TIA/EIA-IS-968 or UL60950. Protected error-free data transmission is the main objective. State-Of-The-Art Solutions Protection is generally implemented using gas discharge tubes (GDT) or a Trisil on the primary side. However, the reliability of GDTs is subject to question and the capacitance of the Trisil is quite often a problem. This results in designers trying to include the protection after the DSL transfor mer. In this case requirements are different, and the key point is to keep the surge voltage below the maximum voltage of the line drivers and not to disturb transmission. Current solutions are either, Metal Oxide Varistors (MOV), zener diodes or small rail to rail diodes. Current Solutions And DSL01 Comparison Key value Surge capability Max voltage Capacitance Technology Quality Ageing MOV Zener Rail-to-rail DSL High Low Low Low Too High Medium Too High Too High Low Low Very Low Low Monolithic Dual dice Monolithic ZNo grain small planar small signal planar on between 2 wire bipolar planar single frame pins bonding wire bonding wire bonding Good Good Very good Deteriorates No No No Yes MOVs provide poor protection after several surges and a degradation of performance can affect transmission. Zener diodes are not protection devices and are unable to avoid high voltage online driver output. Rail-to-rail diodes have too high dynamic forward voltage to limit voltage across line drivers. www.st.com/protection The DSL01 Family Provides The Solution DSL01 does not generate signal distortion and is compliant with GR1089, ITU-T K20/21 when located after the DSL transformer. DSL01 is a reliable planar technology device, with no ageing, and guarantees drivers running to avoid field failure returns. The key added-value of the DSL01 are: High surge capability (IPP) to withstand GR-1089 and ITU-T K20/21 after the DSL transformer Low voltage during surge (VCL) to avoid line driver damage Low capacitance to ensure data integrity The ASD technology which combines two main functions on one chip: clamping and crowbar protection. A Transil ensures low energy surges while a Trisil short circuits high energy surges to ensure low voltages. DSL01 has been developed in 8 V and 16 V versions to be used in tripolar protection while some modems require only common or differential modes (other voltages are in development). + DSL01 DSL01 DSL01 + Tripolar protection for DSL line drivers Product Range Part number Package Leakage current Breakdown voltage DSL01-008SC5 Ir<500 nA at 8 V Vbr>9.5 V at 1 mA SOD23-5L DSL01-016SC5 Ir<500 nA at 16 V Vbr>18 V at 1 mA C max at 0 V bias 20 pF 15 pF 8 By F. Criscione Power MOSFET Marketing STD55NH2LL Power MOSFET HIGH SIDE SOLUTION TO BOOST SYNCHRONOUS BUCK CONVERTER EFFICIENCY The increasing demand for greater power from the latest CPUs means that synchronous buck converters used in Voltage Regulator Modules (VRM) and POLs must have very high performance in terms of overall electrical behavior during switching transients and ON state. This demand may be satisfied by using low voltage Power MOSFETs in VRMs with very low gate charge (Qg) and low on-resistance RDS(on). The efficiency of the overall system can be improved with STD55NH2LL, ST’s new high side Power MOSFET, in the synchronous buck converter. STD55NH2LL General Features R DS(on) * Qg industry’ benchmark Conduction losses reduced Switching losses reduced Low threshold device High avalanche ruggedness Low gate drive power losses Device Comparison In order to demonstrate the benefits of using STD55NH2LL, a test was performed on the L6710 controller demoboard assuming the same low side switching and the following conditions: Vin = 12 V Vout = 1.5 V 2 phase: 1xHS, 2xLS Tamb = 25 °C fsw = 440 kHz The comparison made against two similar high side Power MOSFETs in DPAK, shows that the STD55NH2LL is an optimum solution to boost the efficiency by 1% in synchronous buck converters.

La Mantia Power MOSFET Marketing 650 V & 800 V MDmesh TM IMPROVED Power MOSFET RDS(on) BOOSTS ADAPTER EFFICIENCY ST has recently introduced the new 650 V MDmesh II and the 800 V MDmesh I series as a response to the increasing demand for higher efficiency adapters in the 75 W up to 230 W power ranges. The types of Power MOSFETs chosen by adapter designers differentiate themselves in breakdown voltage and maximum on-resistance depending on the topology and the range of power involved. In fly-back single switch adapters designers may use 600 V to 800 V Power MOSFETs. 650 V MDmesh II Main Benefits The range of V GS used to drive the 650 V devices has been lowered (threshold voltage range Vth: 2 V<Vth < 4 V) keeping the same threshold spread (2 V), ensuring high noise immunity that prevents the circuit from accidentally switching. An energy-optimized driver circuit enables the Power MOSFET to drive higher currents at a lower voltage gate threshold.

When designers require higher breakdown voltage levels, the 800 V MDmesh devices are the right choice for the most demanding high efficiency adapters. In fact, thanks to STs' Super-junction technology 800 V devices greatly reduce switching losses. 650 V MDmesh II Key Features Standard packages TO-220, D 2 PAK, I 2 PAK, TO-220FP and TO-247 Avalanche ruggedness Gate charge minimized Very low intrinsic capacitance Very high speed switching Extreme dv/dt rated Exceptionally low RDS(on) www.st.com/pmos Vinac DC-DC CONVERTER (FLYBACK) Typical adapter schematic using a DC-DC converter in flyback topology 650 V and 800 V MDmesh Product Range Part number BVDSS RDS(on) max ID (cont) STx10NM65N* 480 mΩ STx11NM65N 650 V STx15NM65N STx20NM65N STx7NM80 800 V STx11NM80 380 mΩ 270 mΩ 190 mΩ 1.05 Ω 0.4 Ω 12 A Package DPAK, IPAK, D2PAK, TO-220/FP 11.9 A D2PAK, I2PAK, 15.5 A TO-220/FP, TO-247 19 A 6.5 A TO-220/FP, DPAK, IPAK 11 A TO-220/FP, D2PAK, TO-247 Note: 650 V devices = MDmesh II technology, 800 V devices = MDmesh I *Q1 2008 800 V MDmesh I Main Benefits Thanks to its extremely low on-resistance per area, the 800 V device is recommended for PFC in lighting, adapters and the most high efficiency converters for switching applications.

Viola Power Bipolar Marketing MDxxx Series NEW SERIES OF HIGH VOLTAGE BIPOLAR TRANSISTORS FOR SLIM CRT DISPLAYS Benefits Major benefits for MD products are: Tighter hFE range Improved R.B.S.O.A. for safer switching performance Reliable very high-voltage breakdown Very low leakage current Low power dissipation Cool working temperature Stable thermal performance vs driving variation Better compatibility for easy replacement Part Numbering Description Although traditional CRT (Cathode Ray Tube) displays have lost ground in recent years to flat screen displays based on LCD (Liquid Crystal Display) or PDP (Plasma Display Panel) technologies, CRT technology continues to offer the best trade-off between picture quality and cost. ST’s new MDx family of high voltage power bipolar transistors is specifically designed to meet the challenging requirements for horizontal deflection in slim CRT displays. Because these new displays employ picture tubes of significantly reduced depth, the angle through which the electron beam must be deflected during each horizontal scan has increased from 110° to typically 124°. This obviously places stringent new demands on the bipolar power transistors that control the flow of current through the horizontal deflection coils. To meet this requirement, the MDx devices are built with the EHVS1 state-of-the-art technology. MD Built-in diode (if present) 4 digit identification (same as the STxxx series) FH: TO-220FH FX: TO-3PF Medium/standard definition MDxxx series nomenclature MD Series Product Range In TO-3PF Part number Diode VCES [V] MD2103DFX MD1802FX MD1803DFX EHVS1 Technology And Features MD2001FX EHVS1 is a planar technology realized by a float-zone collector on a diffused substrate, with a redesigned high voltage edge structure. The silicon efficiency has been improved thanks to the reduction of the capacitance in the base-collector junction by adopting a special deep-base process. As a result, MD devices offer: Both high current capability and high switching speed A wider range of optimum drive conditions A reduced saturation voltage at high current MD2009DFX www.st.com/bipolar FH/FX D 1803 MD2310FX IC [A] Target use 6 up to 21" 10 up to 29" 12 up to 32" 14 up to 36" 1500 N.B. These parts are also available in TO-220FH, identified by last digit H, instead of X (i.e. MD2103DFH) Applications Besides being primarily aimed at horizontal deflection in slim CRT displays, both MD1802FX/– FH part numbers are also very cost effective in TV power supply applications (RCC topology). They are suitable for TVs with screen sizes in the range 14” to 25”. 12 By F. Fisichella Power Bipolar & IGBT Marketing STGxL6NC60D IGBTs NEW HYPER-FAST 600 V PowerMESHTM IGBTs FOR HIGH FREQUENCY APPLICATIONS STGPL6NC60D Main Features And Benefits IC @ 100 °C = 8 A Low Cres / Cies ratio VCES = 600 V (min) VCE(sat) @ 125 °C = 2.1 V (typical) Co-packaged diode Low conduction losses Low turn-off switching losses Very high operating frequencies No cross-conduction susceptibility Trade-off between cost and performance STGPL6NC60D Power MOSFET #1 Power MOSFET #2 8 4.4 5.6 VCES / VDS [V] RDS(on) @ VGS = 10 V [Ω] VCE(sat) @ TC = 25 °C VGE = 10 V IC = 3 A [V] 600 500 500 1.22 0.93 2.1 - Performance comparison between STGPL6NC60D and standard technology Power MOSFETs www.st.com/igbts High frequency ballast 2x54 W schematic The system used in the analysis was a 2 x 54 W (with T5 tube) high frequency ballast typical to lighting applications. The switching frequency was 43 kHz, and the inverter topology was realized with a half bridge configuration. In this application by only increasing the snubber capacitor (Cs), STGPL6NC60D showed much better thermal behavior. By increasing Cs, the junction temperature (Tj) decreases. Since the power dissipation is proportional to Tj, lower temperatures mean lower power dissipation. Power loss [W] In order to evaluate the performance of the new device, a preliminary comparison was made between the new STGPL6NC60D and two standard technology (non superjunction) Power MOSFETs. IC @ 100 °C [A] STGPL6NC60D STGPL6NC60D’s total power dissipation is much lower than that of MOSFET #1. STGPL6NC60D shows lower on-state power losses, but being slower than the MOSFET, STGPL6NC60D shows higher switching losses. Since MOSFET #2 has a much bigger die area than STGPL6NC60D, the same thermal behavior was seen. STGPL6NC60D vs. Power MOSFETs Device STGPL6NC60D L6569 This new extremely fast switching IGBT (20 ns @ 100 °C has) been designed specifically for very high frequency applications such as high frequency ballasts, SMPS and PFC (also hard switching). Based on ST’s proprietary PowerMESH technology and benefiting from a new lifetime control technique, this new device exhibits very low turn-off energy (4.5 μJ @ 1.5 A, snubber capacitor 2.7 nF). An optimum trade-off between on-state voltage and switching losses allow very high operating frequencies. It represents an ideal solution in hard switching and in resonant topologies where high performance is as essential as cost. Four package options are available for this device: DPAK - STGDL6NC60D - STGBL6NC60DT4 D2PAK TO-220 - STGPL6NC60D TO-220FP - STGFL6NC60D SWITCHING CONDUCTION SWITCHING CONDUCTION Power MOSFET #1 STGPL6NC60D Comparison between the total power dissipation, (conduction and switching losses) of STGPL6NC60D and Power MOSFET #1 (similar die area) Excellent Cost Performance Trade-off Experimental data shows that STGPL6NC60D realizes the best trade-off between cost and performance; in other words, it is able to offer better performance than MOSFETs with the same silicon area, and similar performance to bigger MOSFETs. 13 By Y.

Menescardi Industrial and Power Conversion Marketing L6566 Multi-Mode Controller VERSATILE CURRENT-MODE PRIMARY CONTROLLER IC FOR HIGH-END ADAPTERS AND FLAT TVS L6566 is a new, extremely versatile current-mode primary controller IC specifically designed for high-performance offline flyback converters. Both FixedFrequency (FF) and Quasi-Resonant (QR) operation are supported by the same product; the user can pick either depending on the application requirements. L6566 is a multi-die product, including a high voltage section (HV start-up) in BCD off-line technology and a low voltage section (the core of the controller) in BCD6 technology, mounted together in a small, standard SO-16N plastic package. Functional Description The device features an externally programmable oscillator which defines the converter’s switching frequency in FF mode and the maximum allowed switching frequency in QR mode. When FF operation is selected, the IC works like a standard current-mode controller (UC384x-like) with a maximum duty cycle limited at 70 % min. QR operation, when selected, occurs at heavy load and is achieved through a transformer demagnetization sensing input that triggers the Power MOSFET’s turn-on. With a very small load, in FF or QR operation the IC enters controlled burst-mode operation that, along with the built-in non-dissipative high-voltage start-up circuit and a reduced quiescent current, helps keep the consumption from the mains low while meeting the most demanding energy saving regulations. L6566A And L6566B L6566 is supplied in two orderable versions, L6566A and L6566B. L6566A is specifically designed for offline flyback converters operating from a front-end Power Factor Corrector. The L6566A provides an interface with the PFC controller that turns-off the pre-regulator at light load. L6566B is designed for offline flyback converters where a front-end PFC is not expected. L6566B has a frequency modulation input that modulates the oscillator frequency. This modulation is used to reduce the peak value of EMI emissions. www.st.com/powermanagement Main Features And Benefits Selectable multi-mode operation On-board high-voltage start-up Low quiescent current (< 3 mA) Adaptive UVLO Line feed-forward Pulse-by-pulse OCP Transformer saturation detection Latched or autorestart OVP Brown-out protection Component count minimization Fits all world-wide energy regulations Rectified mains voltage Vout DC PFC controller Rectified & filtered mains voltage L6566A L6566B Vout DC System block diagram Typical Applications Hi-end AC-DC adapter / charger LCD/CRT monitor, LCD / CRT TV Digital consumer Single-stage PFC Evaluation Boards EVAL6566A-75WADP EVAL6566B-60WADP AC-DC adapter with PFC AC-DC adapter without PFC 16 By A.

Valvo Voltage Regulator & Interface Marketing STLQ50 Voltage Regulator 50 mA, 3 μA SUPPLY CURRENT LOW DROP LINEAR REGULATOR EXTENDS BATTERY LIFE The optimization of the low quiescent current in power supply designs has become of great importance. A long battery life is essential and depends on the consumption of the power supply at a given load. One way to decrease the consumption especially at low output loads is to minimize the quiescent current of the power regulator IC. There are portable applications where the device is required to work at full load for a very short time only, while it has a very long stand-by time. In this case a very low quiescent current helps. STLQ50 Description As a result of this market demand, ST has developed the STLQ50, a BiCMOS linear regulator specifically designed for operating in environments with very low power consumption constraints. Due to the very low quiescent current (3 μA) the device extends the battery life in applications with a very long stand-by time. The Power MOSFET pass element also allows a very good drop-out figure (200 mV at 25 mA I out and 350 mV at full load) without affecting the consumption characteristics. Main Features 2.3 V to 12 V input voltage range 50 mA maximum output current 3 μA quiescent current Available in 1.8 V, 2.5 V, 3.3 V, 5.0 V fixed output voltage and in adjustable version 200 mV dropout voltage at 25 mA output current Internal thermal protection Small SOT323-5L and SOT23-5L packages Small Packages ADJ GND V bandgap 1.22 V OUT + STLQ50 N/C ADJ IN Short circuit and thermal protection Adjustable Vout Vin Fixed Housed in the very small SOT323-5L (SC-70) and SOT23-5L packages, the device fulfils the space saving requirements of battery powered equipment.

Lupo Voltage Regulator & Interface Marketing STULPI01 Transceiver ULPI COMPLIANT, USB2.0 HIGH SPEED TRANSCEIVER WITH OTG FUNCTIONALITY ULPI Standard Minimizes Pin Count ULPI stands for UTMI+ low pin interface and is designed specifically to reduce the pin count of discrete high-speed USB PHYs. Pin count reductions minimize the cost and footprint of the PHY chip on the PCB and reduce the number of pins dedicated to USBs for the link controller. As a result of these capabilities, ULPI is quickly becoming the new interface standard among system and chip designers. STULPI01 is a stand-alone solution able to add a high speed USB connection in Application-SpecificIntegrated-Circuits and System-on-Chips where fast data exchange rate, complexity and low power consumption are a main concern. The STULPI01 is a high speed (480 Mbps) USB 2.0 transceiver which is compliant with ULPI (UTMI+ Low Pin Interface) and OTG (On-The-Go) specifications, providing a complete physical layer solution for any high speed USB host, device or OTG dual role core. STULPI01 is optimized for low power consumption, and minimal die/package dimensions. OTG Functionality: The Intelligent Solution m www.st.com/interface m Unlike full- and low-speed USB systems which utilize serial interfaces, the high-speed STULPI01 solution requires a parallel interface between the controller and the PHY in order to run the bus at 480 Mbps. This leads to a corresponding increase in complexity and pin count. ULPI keeps this down to only 8 or 12 signals because it combines just three control signals, plus clock, with a 4 or 8-bit bi-directional data bus. The 4 and 8-bit modes are known as double (DDR) and single data rate (SDR) respectively. 6 DDR Or SDR Mode Supported Supports 480 Mbit/s high-speed, 12 Mbit/s full-speed and 1.5 Mbit/s low-speed modes of operation.

Chang Advanced Logic Marketing SIMPLE LOW COST SOLUTION FOR TOUCH SENSING To address the rapidly growing market of low power touch screens, ST has introduced S-Touch, a new range of touch sensor controllers that can offer simple and highly efficient solutions for capacitive and resistive touch-sensor functions in ultra small packages. S-Touch implements highly innovative signal processing techniques for both capacitive and resistive technology to correctly detect, process and pass the touch information to the CPU. In addition, the sensor lines from the device to the application's touch pads do not require any external RC (resistor capacitor) networks which are typically required in other solutions, resulting in a highly cost-competitive solution. Capacitive S-Touch Controllers S-Touch devices are housed in the tiny QFN16 and QFN40 packages, 80 % smaller than existing equivalent solutions, ensuring a very compact and efficient design. S-Touch capacitive touch-key controllers use a hardwired finite state machine approach with fully digital architecture. This results in very low power consumption, five to ten times lower than the conventional touch sensor solution, and ultra fast sampling time, typically 2 ms.
